The short version

  • Each has a real cost: .NET .NET 8 and .NET 9 both reach end of support on 10 November 2026, per dotnet.microsoft.com/en-us/platform/support/policy (Aug 2026), forcing an upgrade to .NET 10 by that date; Node.js slower cold-start time in serverless environments compared to Bun which wakes up in under 5ms

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

.NET

  • .NET 8 and .NET 9 both reach end of support on 10 November 2026, per dotnet.microsoft.com/en-us/platform/support/policy (Aug 2026), forcing an upgrade to .NET 10 by that date
  • Standard Term Support releases get only 2 years of patches versus 3 years for Long Term Support releases, per Microsoft's own support policy page, so teams on an STS release face a shorter upgrade cycle

Node.js

  • Slower cold-start time in serverless environments compared to Bun which wakes up in under 5ms
  • Requires separate setup for TypeScript support unlike Deno which treats TypeScript as native
  • Larger memory footprint on startup compared to lightweight alternatives like Deno
